Earth Day, Bogotá
If the idea of car-free capital sounds far-fetched, just take a look at Bogotá. On April 22nd this year, it celebrated Earth Day by permitting only buses, taxis and emergency vehicles to circulate through the city – private cars and motorbikes had to be left at home between the hours of 5am and 7.30pm. Cycling through this city of 8 million people felt relaxed, social and safe. An already impressive tally of 402km bike routes were extended by a further 63km for the day.
